HAND PERFORATOR.

Application iled May 3l,

To all whom t may concern Eo it known that l, HJALMAR SWANsoN, a citizenof the United States, residing in Chicago, in the county of Cook andState of Illinois, have invented a neu'and useful Improvement in HandPerorators, of which the following is a specification.

This invention relates to hand perforators, and has for its object toprovide a simply constructed though .highly eiiicient device of thischaracter which may be carried aroundupon the person of the operator,and which embodies, among other features, provision for punching datathat is changed automatically at each operation of the periorator, thechangeable data being preterably punched in combination with thepunching of non-changeable data. By the invention, a salesman, forexample, or other operator, may punch on successive slips of paper, suchas sales tickets, different data on each ticket, as successive numberswhich are changed automatically at each punching operation, thesuccessive numbers indicating successive sales and being peferablycombined With the punching of fixed dalla on each sales ticket toindicate the particular salesman making the sale. lVhen employed in themanner above set forth, the invention provides perforating equipmentthat is especially suitable for large sales organizations7 such asdepartment stores, in that the use of the improved hand perforator willfurnish a practically unalterablc record of the sales made by eachindividual salesman.

l'n addition to the general objects recited above, the invention hasforiurther objects such other improvements and advantages 'inconstruction and operation as may be found to obtain in the structuresand devices hereinafter described or claimed.

In the illustrated embodiment of the invention, the hand perforator isespecially designed for being used in the manner and for the purposesabove specified and, for

convenience, the present description Will be confined to this use of theinvention.

Features of construction of the hand perforator are, however, capable ofother applications; hence, the scope oi' the invention is not confinedto the specific use and specific embodiment herein described as anillustrative example.

Referring to the drawings: The hand peri'orator embodies in itsconstruction a pair of movable jaw members 11 and 12irespectivelyprovided, at one end With handle grips 13 and 14, and pivoted together,at the opposite end at 15. A spring 16, the opposite ends of which seatin sockets 17 and 18,

provided in the members 11 and 12, maintain said members normally apartfrom each other.l a position in which the several punches are retractedfrom the dies. The sheet or sheets or paper to be punched are insertedin an open slot 19, extending longitudinally in the jaw member 12.Situated in said member 12 at the bottom of the slot 19 is a die plate20, the dies of which communicate with an opening 21 below the die platefor the discharge oi the punched articles of paper.

In the present instance, the die plate 20 is provided with two series otdies A and B, the former co-operating with a punches for periorating thefixed data and the latter col-operating with a series o punches forperi'orating the changeable data. The fixed data dies A are furthermoredivided into two groups aand a tor co-operation with corresponding'groups of iixed data, punches, each said group ot punchescoacting withits corresponding group or dies to perforate a character ot the iixeddata, such as a digit ci a two digit number' designati-ng, or example,the particular person operating the punch. rthe changeable data dies arealso sub-divided into two groups 7) and b, each group co-oierating witha corresponding group oi the change able data punches to perforate acharacter.

The punches 22 are divided into tivo ser A and B', and the series rif, Bare respec tively subdivided into groups of punches 0:? and a3 and Z22and 3; the groups c2 and z3 co-operating respectively with the groupsor" dies a and a, and the groups and 3 co-operating respectively withthe groups dies and in the manner above stated. Both series'of punchesi-i and l" extend into a chamber 23 pro ,d in the jaw member l2, and thelower ends of said punches, when in advanced position with respect totheir corresponding dies extend through perfor-ate. guide plate 2dlocated below the chamber 23 and forming the top of the pa per receivingslot 19. Willen in the retracted position, the upper ends off 'the)anches cxtend through a top guide plate 25, which forms the top of thechamhe The punches 22 are further guided in their advancing' orretracting movement, by a soit metal filling 26 located above the lowerguia e plate 24.

p The punches A of the xed data series are operated by a fixed ornon-adjustable matrix 27, which preferably consists of a plate iixed tothe lower face or" the jaw member 11 and movable to advance the fixeddata punches A into their coresponding dies A, during the operation oitsqueezing together the handle grips 13 and 111- oi the two jaw inembers11 and 12. In the form shown, the matrix 27 is reversely socketed foreach group of punches a2 n?, so that it will series ot Leraars notoperate those punches ot the groups which are not required forperforating the particular characters desired. During the operativemovement of the matrix 27, the punches not required pass idly throughthe reverse sockets in the iixed matrix and only hose punches which arerequired for punching the characters desired are engaged by the face ofthe matrix and advanced into co-operation withtheir respective dies.

The changeable data punches B are operated by adjustable or revolublematrices 29, there being one matrix for each group 52 and 3 oisaidpunches B. The adjustable matrices 29 are preferably constituted ofrings which revolve upon a fixed arbor 30 secured in the bifurcatedportion 32 of the jaw member 13.. Each matrix ring 29 is preferablyprovided with a series of matrix faces 31, preferably ten in number, onefor each of the 9 digits and one for O, the matrix faces 81 being alsoreversely soclreted, so that they will not operate those punches ci' thegroupV which are not required i'or printing` the particular characterdesired. The matrix rings 29 are held in proper position for theoperation orn each oi their matrix faces by positioning` members 28which are moved by springs 33 into one of a series of sockets 34 formedin the inner circumferential portion of each matrix ring. When thepositioning members 32 are seated within sockets 34 of their respectivematrix rings, a matrix face 31 oiE each ring is in proper position foroperating its correspond ing group or changeable data punches.

ln accordance with the invention, provision is made for changing thedata punched by the series of punches B on each operation oit theperitorator. In the present embodt ment or' the invention, which employstwo matrix rings 29, one of said matrix rings functions to punch digitsof the units order, and the other functions to punch digits of the tensorder. Consequently the tens order matrix ring is advanced one numeralspace at each complete revolution of the units order matrix ring, thatis to say,-when ever the units matrix ringis passing from 9 to 0. Toaccomplish this result, provision is also made for transmitting carryingimpulses to the higher order matrix ring each time the lower ordermatrix ring passes from 9 to (l. Secured to each matrix ring 29 is aratchet 35 having ten teeth 36, respectively companion to the digitalmatrix faces ot their respective matrix rings. The ratchets 35 areprevented from rotating reversely by means of back stop pawls 37. Asshown in Figs. 10 and 11 the tooth 37, opposite the 9 matrix face ofthel units order matrix ring is cut deeper than Jthe other teeth 37 ofsaid units order matrix ring, the purpose of this construction appearinghereafter. Secured to the lower Vil lil() .jaw member 12 is an upright38, which supports at its upper end a slideway 39. l/Vorlr` ingwithin'said slideivay 39, is a slide pawl 40, that is yicldingly urgedtoward the ratchets by a spring 41 bearing against said pawl. The pawl40 is provided at its forward end with a relatively long detent 42 forengagement with the teeth of the ratchet ot the units order matrix ringand With a relatively short detent 43 for engagementfwith a tooth ot thetens order matrix ring whenever a carry is to go over from the units tothe tens arder. The detent 42 is made long enough to engage a, tooth ofthe units order ratchet at all times, and such engagement is eifectiveto advance the units order matrix ring, onev matrix tacegat thebeginning oit the operation of squeezing together the handle members 13and 14 ot' the perforator. The other detent 43 of the` pawl is, however,made too short to engage a tooth oi the tens order ratchet, except whenthe tooth 37a of the units order ratchet is positioned to receive thedetent 42, which 4happens when the 9 matrix face of the units order ringis positioned for cci-operation with the punches B. The greater movementallowed the pawl 40 by such positioning of the tooth 37a, brings thedetent 43 forwardly into position for engaging and operating the ratchetof the tens orner matrixcring, during the next operation of theperforator, thereby transmitting a carrying impluse to the tens ordermatrix ring. The completion of the carrying impluse, is accompanied by amovement ot the tooth 37a away from the detent 42, with the result thatthe detent 43 is again retracted into inoperative position, until afurther complete rotation of the units order matrix ring has beenyeffected to require the transfer of another carrying imp-luso. Duringthe retracting movement of the jaws 11, 12 of the perforator, the detentor detents of the paWl 40 pass idly over the ratchet teeth 37.

Provision is alsomade for locking the hand perforator against furtheroperation, when it has been operated to the limit ot its capacity.Formed in the face of each matrix ring 29 is a transverse slot V44, theslots 44 ot the respective rings being in alignment with each other,when the matrix faces are in position for punching the highest numberthat may be punched by the pci-iterator, in the present instance, thenumbei' 99. Supported ina chamber in the upright 38 Ais a spring pressedstop pawl 45 which moves into the aligned slots 44 and prevents furtherrotation of the rings 29, as soon as` said rings have arrived at theabove designated punching position. The locking of the rings by the pawl45 prevents setting ot the perforator to begin another series otpunching operations. rRelease of said rings is eiected by means or areleasing rod 4G rotatably mountcdin the pper jan' member 11 anilprovided'with a ug 7,

member 49 secured to the side :tace oi the upper Jaw member 11.. .Anordinary padlock may be inserted into tno holes of the locking members48 and 49 te prevent the release ot the pawls 45 and re* setting of thematrix rings, except by one having the authority to do so.

ln order to prevent accidental operation of the hand pertorator, whencarried about on the person et the operator, there is provided means formaintaining the jaw mein bers 11 and 12 normally in their retractedinoperative position. Pivotally secured to the lower handlegrip 14 is anarm 51 which passes upwardly througl'i a slot 527m the upper handle grip13. Near its upper end the arm 50 is provided with a shoulder 53 adaptedto engage a. lug 54 carried by thc upper handle grip 13 for the purposeof maintaining the handle grips 13 and 14 and the jaws 11 and 12normally retracted from. each other. A spring 55 maintains the shoulder53 normally in vengagement with the lugs 54. Whenever it isdesired tooperate the punch, the operator may by the movement ot his thumb tiltthe arm 50 for ward slightly, so as to disengage the shoulder 53 fromthe lug 54, with the result that the arm 50 will pass freely through theslot 52 in the upper handle grip 13.

When pressure is released from the handles 13 and 14 of the jaw .members11 and 12, the spring 16 restores said jaw members to their retractedposition. The move ment of the members 1l andk 12 to such retractedposition is accompanied by a concurrent restoration ot the previouslyoper ated punches ot both series A and B to their normal position. Forthis purpose, each punch 22 is provided with a fixed collar 56, adaptedYto be enga ed by the upper face of a perforate plate 5r, through whichthe several punches extend. The plate 57 supported by side members 58carried by the jaw member 11, and, as the latter moves away from theother jaw member 12, the plate 57 engages the collars 56 of the severalpreviously operated punches and restores them to their normal. retractedposition.

The invention as hereinabove set forth is embodied in a particular formof construetion but may be variously embodied within the scope of theclaims hereinafter made.
